GRAIN-BINDER.

SPEOIFICATIQN forming part of Letters Patent No. 264,602, datedSeptember 19, 1882.

Application filed December 8, 1881. (No model.)

IO My invention relates to an improvement in that kind or type ofself-bindersin'which the continuously-running mechanism that drives theneedle-arm and other devices for binding into a sh'eaf the collectedgavel is periodically thrown into gear with said devices through themedium of some device actuated by the pressure on it of the grain whichis being collected or gathered within and packed in the gavelreceptacle. e

In mechanisms of this type as made previous to my invention it has beencustomary to have the device, which is actuated by the pressure on it ofthe grain packed into the gavelreceptacle, located at or near the lowerpart of said rcceptacle,.or, in other words, near that end of thegavel-receptacle at which the bound sheaf makes its exit from saidreceptacle. In machines constructed upon this principle there is aliability (in the cutting and binding of some kinds ofgrain) of thegrain collecting and being packed in the gavel-receptacle to an extentbeyond that contemplated or designed, whereby, instead of. the devicefor actuating the tripping mechanism acting at the proper time,it is notactuated until a too great collection of grain has been effected, andthus an unusual and unnecessary strain is brought on the bindingdevices, and a too large sheaf is formed. There is also a liabilityinmachines organized on this principle of an utter clogging and stoppageof the machine by reason ,of some kinds of materials-such as sticky wetgraingetting wedged into the gavel-receptacle in such a manner as tofail to get packed down against the actuating device so as to moved, andthus set the binder devices properly into motion.

My invention has for its object to entirely overcome these defects ofthe type of selfbinders referred to; and to this main end and object myinvention consists in the employment of one or more of the packing-arms,or

some other device operating to press the grain toward the discharge endof the gavel-receptacle (instead of a device located at or near thedischarge end thereof) for the purpose of transmitting the pressureapplied to force the grain into the gavel-receptacle to the trippingmechanism for throwing the driving mechanism of the binder into gearwith the'needle-arm and other devices for binding the sheaf, and thusoperating said devices at the proper times, all

as will be hereinafter more fully explained.

To enable those skilled in the art to which my said improvement relatesto make and use 6 my invention, I will now proceed to more fully explainit, referring by letters to the'accompanying'drawings, forming part ofthis specification.

Asmy present invention relates wholly to the novel'contrivance or meansfor tripping into gear with the driving mechanism, or for properlystarting into action at the right times the binder devices, I need showand specially explain only those parts of a binder which are associatedwith the contrivancc alluded to; and as I have in practice applied mypresent invention (by a slight alteration of the machine) to aself-bindersuch as shown and described in general in my United StatesLet- 8o ters Patent, No. 212,420, February 18, 1879, and with someimprovements in another application filed by me June 29, 1881, and nowpending inthe Patent Office-I have shown at x Figures 1 and 2,respectivel v, a side view and a '8 5 vertical section of the binderattachment for harvesters shown and described in my said otherapplication, while at Fig. 3 I have shown a partial top view of saidbinder with my present improvement appliedthereto; atFig. 9o 4, apartial side view of the improved contrivance seen at Fig. 3; and atFig. 5, a view 0t the same, looking in the direction of the arrow whenthe needle-arm O carries the bindingcord partially around the gavel, atthe same time (in conjunction with the compressing-fingers I)compressing the gavel, while the tying mechanism ties up the gavel intoa sheaf, and the latter is discharged from the machine in a manner whichis well known, and which, in view of my patent and other application,does not need further explanation here.

D is the main driving and continuously-rotating shaft of the bindermechanism, and is rotated by a sprocket-wheel, E, arranged thereon, andbelted by a chain-belt to a main driving-wheel and shaft of theharvester. The said shaft D is provided with the cranks GG, that drivethe packers B B in the manner shown and described in my otherapplication, above alluded to, and the chain-wheel E has its hub emounted to turn freely on said shaft, but clutched to a sleeve-piece, h,which, though capable of a slight sliding movement lengthwise of shaftD, cannot turn thereon, and thus through the medium of said sleeve-pieceh the chain-wheel E drives the shaft D.

a is the trip lever or arm, which has to be slighty lifted at its upperor free end in order to liberate the spring-dog I), that rests on thesaid end of said lever a,.for the purpose of throwing the drive-pinionof shaft D into gear with the train of spur-wheels that operate thedevices for binding and tying up and discharging the sheaf. The relativepositions of the parts a and I) seen at Fig.4 are those occupied whilethe shalt runs without driving the binder devices proper; and those seenat Fig. 1 are the positions of these parts after the tripping and whilethe mechanism is all running, as will be understood without furtherexplanation here.

In my former machine, as patented, this lever a was vibrated about itsaxis or shaft J through the medium of an arm, 61, (see Fig. 1,) fast ona rock-shaft, 0 that was slightly turned by arod and lever connected tothe compressorfingers I; while in said former machine,as improvedaccording to my pending application, the rock-shaft e is moved oractuated from an auxiliary finger, S, (see Figs. land 2;) butacjectingear-like portions t' of the sleeve It, so

that any longitudinal movement of saidsleeve on the shaft D in thedirection indicated, for instance, by the arrow at Fig. 5 will slightlydepress the free end of arm f and force shaft 6 (to which the other endof arm f is rigidly secured) to rock or slightly turn on its axis, thuscausing the arm (1, fast on the outer end of shaft 0 to move suficientlyto act on the projection a of the hub of trip-lever a and operate it inthe desired manner.

The sleeve-piece h is caused to slide on shaft D in the direction of thearrow at Fig. 5 under circumstances and by the means I will now explain,and is returned always to its normal position by a strong spiral spring,m.

On the hub or collar portion 6 of the chainwheel E are arranged atpoints diametrically opposite two little radially-projecting studs, 1,on which are mounted anti-friction rollers 2, and these rollers2 areaccommodated in cavities or cut-outs made in opposite portions of thethimble-like part of sleeve h, as clearly shown. These cut-outs haveinclined cream-shaped surfaces M3 3, along which the rollers2 have atendency to ride, as they operate, clutch-like, to retate said sleeve.This tendeneyis overcome by the pressure endwise against the oppositeend of sleeve hof the strong springm, and hence so long as a givenresistance only is offered to the turning of sleeve h by the rollers2,seated.

in the cut-outs referred to,said rollers will act to simply clutch thehub e of wheel E to the sleeve h and rotate the latter with said hub,(and since sleeve h, by reason of pin s and slot t, cannot turn on shaftD, the latter is duly rotated also";) but whenever a greater degree ofresistance to the turning of sleeve h is offered than that mentioned,then the rollers 2 will ride up the cam-like faces3 of the cut-outs,thus forcing the sleeve h in the direction indicated by the arrow atFig. 5 and producing the effect already explained. Now, as the firstwork done by the shaftD is the driving of the packers B B, it will beclear that by making (or adjusting) the capacity of the spring so thatitwill yield to the tendency of sleeve H to slide only when theresistance offered to the pack ers shall have become so great as torepresent the maximum compression of the grain in the gavel-receptaclenecessary to form a givensized sheaf, the sleeve It will slide onlyunder that condition of facts, and that thus the tripping device will beoperated only at the desired time. I

It will be seen that with a machine made according to my presentinvention the binder devices will certainly be thrown into operation andthe gavel bound and discharged whenever a sutficient quantity of grainshall have been packed into the said receptacle with the predeterminedpressure, irrespective of whether the packed grain shall have beenproperly forced into contact with the fingers I, that are designed toco-operate with the needle-arm, or shall have (improperly) gotten wedgedhard between the upper and lower sides or surfaces of thegavelreceptacle, asit is liable to sometimes do; that therefore allliability of any clogging, stoppage, unnecessary and hurtful strain onthe machine, or undue work by or strain on the team are effectuallyavoided, for the moment the packers begin to work harder than theyshould prior to the requisite compressing-force for a full-sized sheafthis burden on the drive-wheel E, which,

IIO

through its yieldingclutch-like devices, is driving the shaftD and itspackersB B, will cause the sleeve h to be shipped endwise and the binderdevices proper and sheaf-discharging devices to be set into operation tobind up and discharge in a sheaf the collected and dulycompressed massof grain.-'

It will be understood that the gist of myinvention rests in anorganization'snch that the' pressure existing between the'batch of grainbeing compacted in the gavel-receptacle and a device or devicesoperating to pass it down into said receptacle shall operate to actuatethe devices or mechanism for tripping into action the sheaf binding anddischarging-moch anisms, in contradistinction to all previousorganizations made on the principle of utilizing. the pressure of thecollected mass on some device toward and against which the incominggrain had to be carried, and it will be seen that this novel feature ofconstruction of the lates may be carried out in other forms thanthatY'shown.

l have shown that mode of carrying out the broad invention made by mewhich 1 have thus far devised and put into practical operationsuccessfully, and which is well adapted to the form of machine (of thetype alluded to) that I have heretofore devised and am putting into verygeneral use; but I desire to be understood as considering the scope ofmy invention as covering not only the particularmeans shown fortransmitting the undue pressure on the arm or arms (that force thegraindown into the gavel-receptacle) to -the tripping device, but also anyorganization of devices in which the described novel principle ofconstruction may be embodied i. 0., a con struction in which thetripping device or the means employed to' throw the driving mechanisminto action on the binder devices proper shall be operated from the armsor device which presses the grain down into the gavelotherpendingapplication filed by me, are hereby disclaimed in this case; and

What I herein claim as new, and desire to secure by Letters Patent, is-

1. In a machine in which the grain is collected and compressed within agavel-receptacle by the action of a packing arm or' arms, thecombination, with said gavel-receptacle and said packing arm or arms, oftripping mechanism for throwing the binder devices periodically intooperation, actuated by said arm or arms whenever the latter meet withsuch degree of resistance as will prevent them from traveling farther inthe path of their packing movement in packing the grain into saidreceptacle, substantially as set forth.

2. In a machine of the described type, the combination, with the packingarm or arms and the trip-lever, of an intermediate mechanism for causingthe said arm or arms to actuate the said lever, composed essentially ofa drive-wheel mounted looselyon the drive-shaft of said arm or arms, asliding clutch device mounted to slide on said shaft, and held in closeworking relation with the said wheel by a spring, and the means forcommunicating the sliding movement of said clutch device to thetrip-lever, all substantially as hereinbefore set forth.

In testimony whereof I have hereunto set my hand this 17th day ofNovember, 1881.
